7 '0 all whom it may concern." v

Be it known that I, MAGNUS LAnsnN, a citizen of the United States, residing at Armstrong, in the county of Emmet and State of Iowa, have invented new and useful Improvements in Wagon-Dumps, of

which the following is a specification.

The object ofthe invention is to provide an automatic wagon dump particularly designed for the unloading of grain from.

wagons. To this end the invention comprises a platform in; which is s'wingingly mounted a frame designed to. receive the wheels of a wagon. This frame is mounted so that it may be oscillated to lower one end 7 of the wagon, thereby depositing the con tentstiiereof." The frame is secured firmly in position except at such times as it is'desired to dump the wagon and there is associated with the operating mechanism of the frame, a means for automatically returning the frame to normal position. after the wagon has once been dumped. V v

Other and further objects appear in the following description whereinthe invention is set forthin detaiL- To the exact construction in which it is shown. and described5 the invention is notto, be restricted. The right is reserved to make such changes or. alterations as the. actual reduction to practice may suggest, in so far j as such changes or alterations are compati ble inspirit with the annexedclaims.

entrance platform 2. The platform 1 is formed with the longitudinal slots 3 spacedv plane its'upper face is flush with the top face of the platform 1. It is pivotally mounted substantially at the center of its length and to this end the legs of the frame on the under surface are provided with .laterally underside or surface of the platform. A stop 8 is mounted on the under side of the platform .1 and the transverse portion of the frame 5 strikes this slot-to preclude the passingdownwardly of this portion of the frame through the slot. qThus while-the frame is projecting pivot studs 6 whichloosely engage in bearing members 7 secured tov the mounted for oscillating movement, this" v oscillating movement may take place only on oneside of the pivot point on which it is. naounted.

The platform 1 at that end of the frame 5' remote from the transverse memberis 'fo'rrned with an opening which is closed bya removable trap door 9. This isfor the purposeof permitting teams to enter the platform and dumping the contents of their wagons after the same have passed upon the I frame 5, the contents. of course, being deposited not on top of but below the platform 1.

fit is intended that the platform 11 shall.

i be built adjacent to'a sidewall. but if it is not convenientto thu' position the platform,

it may be built at a point awav from any wall but in such a case should be provided with, a sidewall 10 which may beattached .to the platform in any acceptable manner. a On this side wall 10 there is mounted a bracket 11, the latter having an outboard bearingsupport 12 in which there is 'journaled oneend of a shaft 13.the latter having at the other end .a suitable bearing between the outboard bearing support 12 and the wall 10 there is carried a wheel 14 the periphery of which is frictionally engaged by a brake lever, 15 pivotally mounted at'one'Zend-in asupporting bracket 16 Car- I ried by the bracket 11; The remaining end of this lever 15 is formed with a handle'for the convenience of hand manipulation and the lever may be engaged with or disengaged from a latch member 17 carried on the Wall- '10. A spring :18 attached at one end to the lever 15 and the other end to the bracket 11 tends normally to keep'the brake lever away from the Wheel 14.

The. Wheel 14: serves the purpose of a brake element and tothat end is fixedly at tached to the shaft 18 but besides this brake \vhe el the shaft 13"carries' a drum 19 which is losely mounted on the shaft but precluded from longitudinal movement thereon. On' that Y end facing the Wheel 14, the drum n is formed "with a plurality of inset ratchet passfrom' below; the platform to uiedr'um teethjQUand these are engaged by a spring held 'pa vl21 carried by the ivheel ll; This construction provides for a relative angular movement between the drum and the vvheel when the drum is turned in one direction but precludes suchangularmovement When the drum 1sturned in the'oppfosited rect on.

Eneircling the drum th'ere'is a cable'22 one end of which connects with the eye 23cm:- ried the transverse member of the frame 5. ln'passingrfrom the frame to this eye the cable is trained over the pulleyfltattached beneath'the platform and is further trained over a pulley 25 mounted on the under face'of'theplatform direct-lybelow theeye 23. In orderthat the cable may openinggorrholeflfi-is formed in {the platform 1. To the remaining end 'of the 'cable 22 there is, attached a counter-vveight 2T and the cable fixedly Y secured to the drum substantially an intermediate point between the counter-weight and its point of attachment with the eye23Q It s obvious from this construction that as-the drum turns in one" direction that end o f the cable carrying; the Weight unwinds therefrom and that end attached to the frame 5 "is wound thereupon. The re verse ,turningnmovement of the drumunwinds'that parft'ofthe cable connected to the name but windsaipl that part connected to the counter-Weight. 'lhus if the frame is in a po sition wherethe, transverse portion'ds raised above 'the platform- 1, the counterweight will, be elevated because its :portion 1 of vv'illbe Wound on the drurrr and the remaining. portion of the cable an} wound'amenem. But the countereight ls provlded for the purpose ofkcepmqthe frame normally in its lowerposition Therefore, if there as nothing to retain the frame elevated, the countereight will act to rotats thefdruln'jtvith the result thatthe 'porotion of the "cable connected withthe frame will vvound on the drum and-theframe thereby: pulled do vvninto normal; position. The pawl 21 is so positioned that such a the cable if the force tending to keep the frame'elevated isremoved and the frame is allowed to drop In the operation of the invention,- it is 7 the purpose to drive laden teams up the cntrance platform'so that'the wagon wheels may be made to re'ston the frame trap door 9 is then raised buttho frame is precluded from moving because the brake lever is engaged by the latchme'mbe'r 17 and the wheelll l is thus preventedfrom moving and hence the platform maynot'move becausethe'pavvl 21 engages the teeth 20" to evnt angular movement of the drum 3 5 in the"di'rec'tion' in which it'would' haveto move ifthe' frame were raised by any force applied to that portion of the'eable attached 7 to it." Thus "thewagon having been'po'si tioned on the frame 5,the operatorcharged with the care of dumping the Wagon, mi

release the lever 15 from the catch and relieve as pressure on the heel 1a suiii' ciently. to perinitthenveight of the wagon to rockithe frame '5in' a direction Whichl Will move its rear end downwardly. When the desired angl'e-has' beeii reached, the conthe latter is, of course; moved doavn to its normal position, at Whichtiinethe counter-- Weight operates to take up the slack'on the cable 22 preparatory to the frames receiving another vvagon for dumping. a r
